Process DP Background Processing, variant XXX BG JOB Y has status Undefined (Instance)

Dear Experts

I see this message in job log.

Message Class RSPC, Message 009 that I see is a genetic message in 101 contexts in BW related scheduling jobs. Process chain terminates (status = R)

The variant in question is a DP background job.

What does this message possibly mean in English ?

SCM latest version, latest EhP

Thanks

BS
